PRODUCT BROCHURE
Inspired by the ancient godde of the dawn, this collection embodies her youthful yet coanding spirit in both palate and design. As dawn warms from cool azures to fiery crimsons, then mellows into an amber haze, these pieces mirror the shades of daybreak in cities around the world, evoking a kind of strength that is distinctively feminine. Two limited edition pieces, the Livada and Reyna, with their exotic geometric patterns, bring to the collection a cro-cultural reference to the East, and with it pay homage to the evolving dialogue between the two spheres of East and West that is shaping not only the future of fashion, but also our global identity.
New Product Range A Textile s Best Friend This new product range is available in foiled and hot-fix versions, both with a silver reflective layer, resulting in a substantial improvement in the overall visual impact. Ensuring greater light reflection and intensity, the silver layer, combined with our optimised cut, creates a sparkling effect sure to illuminate the forthcoming fashion seasons. Likewise, a new satin layer, available in both foiled and hot-fix versions, also allows for easy and improved application to various textiles. The bottom of each stone is covered by an innovative layer of satin, giving it a white silver look, which not only eases application but also aesthetically enhances the product range. To be sure, the colour of this layer is designed so that its hue does not interfere with the impreion of the stone itself, but rather allows for easy application to transparent materials on which the use of this premium product sensibly fits the luxury concept of the end product as envisaged by the designer.

Good Things Come in Small Packages, and Ours Are New! To make distinguishing Preciosa from counterfeit products easier, we ve improved our packaging to include a number of safety and proof of authenticity features. Make sure to look for the security seal, consisting of the following criteria, when purchasing our components in an envelope or caette, and to use the given QR code available on the envelopes of our new MC Chaton Rose MAXIMA product line to ensure that you are receiving authentic Preciosa crystals. VOID effect This new feature makes it poible to determine whether or not the envelope has already been opened or tampered with. Upon opening the adhesive seal, a repeating VOID sign will appear on its underside as well as on the envelope itself, so that it is impoible to re-seal it without visible damage. Where to Find the Seal You will always find the security seal on both the envelopes and the caettes. Security Seal Features New Packaging Colours The primary security feature is the Preciosa logo, which can be seen from all angles. The image changes from positive to negative based on the viewing angle and light. The negative version of the logo (i.e., the light oval with a dark star inside) is seen head-on, but turns positive and is rotated 90 degrees counter-clockwise (i.e., the dark oval with a light star inside) when the viewing angle changes from head-on. Proof of Origin QR Code Currently available only for the new MC Chaton Rose MAXIMA, there are two levels of authentication, one for distributors and one for the final user. For distributors and those who do not need to open the envelope, simply scan the QR code on the back of the envelope to receive verification via Preciosa s Web application. This QR code is connected to the production batch number and bar code printed on the outside of the envelope. 09 DIRECT VIEW (rotation of 0 ) LEFT VIEW (rotation of counterclockwise) DIRECT VIEW (rotation of clockwise) Grid Under the Logo Another security feature is the new grid located under the Preciosa logo, which consists of three repeating symbols: a small Preciosa logo, followed by PRECIOSA, followed by Made in Czech Republic Supplied Globally. Designed with a linear kinetic effect, each symbol gradually appears and disappears when tilting or rotating the hologram. DIRECT VIEW (rotation of 90 clockwise) For final users and those wishing to open the seal, scan the hidden QR code underneath the envelope flap to receive verification, also via Preciosa s web application. This QR code is unique to every envelope and contains data about the exact content of the envelope. To prevent the re-use of envelopes, the hidden QR code can only be verified once upon scanning a second time, users will receive an Already verified notification from the application.
